Product Description:

The KMS02.1B-A018-P-D7-ET-ENH-SD-ES-FW is a near-motor servo drive built by Bosch Rexroth Indramat within the KMS Electronic Drives series. Mounted close to the actuator, the drive supplies regulated current and position feedback so that servo motors can perform precise motion tasks in packaging, handling, and assembly lines. By relocating power electronics to the machine frame, it reduces cabinet heat load and shortens motor cable runs, which simplifies industrial automation layouts. This arrangement also keeps the power stage close to the motor, reducing the amount of wiring that must be routed back to the main cabinet.

Inside the sealed housing, the DC link is rated for DC 750 V, giving the power stage headroom for rapid acceleration cycles. The drive reads absolute rotor position through the Hiperface encoder interface, permitting fine velocity control without homing moves after startup. Network access is provided through Multi-Ethernet, and the port can be set for EtherNet/IP, PROFINET, EtherCAT, or SERCOS III to match different control platforms. An IP65 enclosure keeps dust and low-pressure water jets away from live components, enabling direct machine mounting. Thermal energy is removed by natural convection, so no fans or liquid circuits are required. This sealed layout is useful where the drive must be installed directly on the machine instead of inside a protected cabinet.

The drive includes Safe Motion, which monitors speed and position internally to support controlled stops without external relays. The Basic performance level indicates conservative current limits that balance output with long-term reliability during standard cycle rates. Because motion monitoring is handled inside the unit, the axis can evaluate operating states locally without separate relay hardware for each function. The unit is Version 1 in Series 02. This combination is suited to distributed servo axes that require compact installation, integrated communication, and local safety-related motion supervision.
